treeView的使用和TableView差不多，不同的是ContentProvider和LabelProvider的實(shí)現(xiàn)接口不同了。下邊是個(gè)例子，看一下相信你就，明白了
class KindLabelProvider extends LabelProvider {
public String getText(Object obj) {
if (obj instanceof Kind) {
return obj.toString();
}
return null;
}
public Image getImage(Object obj) {
// String imageKey = ISharedImages.IMG_OBJ_ELEMENT;
if (obj instanceof Kind) {
String imageKey = ISharedImages.IMG_OBJ_FOLDER;
PlatformUI.getWorkbench().getSharedImages().getImage(imageKey);
}
return null;
}
}
class KindContentProvider implements IStructuredContentProvider,
ITreeContentProvider {
public Object[] getElements(Object parent) {
if(parent instanceof Kind){
return getChildren(parent);
}
return null;
}
public Object getParent(Object child) {
if (child instanceof Node) {
return ((Node) child).getParent();
}
return null;
}
public Object[] getChildren(Object parent) {
if (parent instanceof Kind) {
ArrayList children = ((Kind) parent).getChildren();
return children.toArray(new Node[children.size()]);
}
return new Object[0];
}
public boolean hasChildren(Object parent) {
if (parent instanceof Kind)
return ((Kind) parent).hasChildren();
return false;
}
public void dispose() {
// TODO Auto-generated method stub
}
public void inputChanged(Viewer viewer, Object oldInput, Object newInput) {
// TODO Auto-generated method stub
}
}
